You can also use the windows ui automation framework to achieve this without getting into pinvoke.

        int pidToSearch = 316;
        //Init a condition indicating that you want to search by process id.
        var condition = new PropertyCondition(AutomationElementIdentifiers.ProcessIdProperty, 
            pidToSearch);
        //Find the automation element matching the criteria
        AutomationElement element = AutomationElement.RootElement.FindFirst(
            TreeScope.Children, condition);

        //get the classname
        var className = element.Current.ClassName;

I assume you mean you want to get the class name of the main window of a process.

To do this, you will need to get the handle to the main window using the MainWindowHandle of your Process object, and then use the following interop method to obtain the class name:

[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);

see pinvoke.net for sample code and MSDN for details on the function.
